Eclipse ~ Grails 3 - Docker Container

Eclipse Mars.2 in a Docker container with required plugins for Grails 3 development

• It is based on the work by fghrem, pay him a visit in his docker-eclipse repository.
• I built it based on some suggestions from Ted Vinke's Java Code Geeks article

In a nutshell has the following plugins installed:

• Spring IDE (for YML and Spring boot support)
• Grails IDE (for GSP editing and quicksearch)
• Gradle support
• Docker support (if you're running the IDE from a docker container, why not run other containers from it?)

The following instructions work were copied from fghrem's repository, as they work in the same way

Requirements

• Docker 1.2+ (the image was built and tested in Docker 1.10.3 )
• An X11 socket

Quickstart

Assuming $HOME/bin is on your PATH and that you are able to run docker commands without sudo, you can use the provided eclipse script to start a disposable Eclipse Docker container with your project sources mounted at /home/developer/workspace within the container:

# The image size is currently 1.292 GB, so go grab a coffee while Docker downloads it
docker pull vintec/eclipse_grails3:mars
L=$HOME/bin/eclipse && curl -sL https://github.com/vintecdynamics/eclipse_grails3/raw/master/eclipse > $L && chmod +x $L
cd /path/to/java/project
eclipse

Once you close Eclipse the container will be removed and no traces of it will be kept on your machine (apart from the Docker image of course).

Making plugins persist between sessions

Eclipse plugins are kept on $HOME/.eclipse inside the container, so if you want to keep them around after you close it, you'll need to share it with your host.

For example:

mkdir -p .eclipse-docker
docker run -ti \
           --name eclipse_grails3 \
           -e DISPLAY=$DISPLAY \
           -v /tmp/.X11-unix:/tmp/.X11-unix \
           -v `pwd`:/home/developer/workspace \
           -v `echo $HOME`/.gradle:/home/developer/.gradle \
           vintec/eclipse_grails3:mars

Help! I started the container but I don't see the Eclipse screen

You might have an issue with the X11 socket permissions since the default user used by the base image has an user and group ids set to 1000, in that case you can run either create your own base image with the appropriate ids or run xhost + on your machine and try again.
